Easy and perfect fit for 2017 and 2018 Honda CRV with 1.5l engines. You need a Phillips screwdriver to remove the 4 screws holding the airbox. After that you just remove the old one and put the new one in the same orientation and put the screws back on. Helps the engine breathe which can result in slightly more power and mpg. I recommend changing every few years.
